Title: Cathodically protecting adsorbent-contg. steel vessel - by generating carbonate layer by anode connected to direct current voltage source
Inventor: STUTTERHEIM FRIEDRICH VON DIPL
IPC: B01J19/00
Filed: 1980-10-14
Abstract: A steel container, provided with a granular C-rich adsorbent bed, for water-purification, is protected against corrosion by generating a carbonate-contg. layer on the internal side of the container, acting as cathode. This is achieved by connecting an anode, placed in the adsorbent bed, with a direct current voltage source. The adsorbent-contg. steel container can be used in drinking water processing. The carbonate layer has insulator-like low electron conductivity. Electron flow between C and steel partition and between anode and cathode is prevented. Ion flow between cathode and anode is not hindered, whereby corrosion-protective exchange reactions can proceed on steel surface.

Patent DE-3121354-A1 (DE)
Title: "Controller with settable proportionality range"
Inventor: BADER HORST DIPL ING
IPC: G05B11/50
Filed: 1981-05-29
Abstract: The invention describes a controller having a settable proportionality range, in which a ring is actuated by the pressure differential in measuring mechanisms such as, for example, pairs of bellows and interacts, as a deflector ring, with a pivoted nozzle. According to the invention, the measuring mechanisms are hinged on the ring diametrically opposite to one another and the effective axis of the one measuring mechanism runs radially, and that of the other measuring mechanism tangentially or parallel to the tangential direction. This ensures that the paths traversed by the measuring mechanisms can arise in a manner decoupled from one another and thus the drawbacks of known designs can be avoided, that the controlled variables influence one another and, owing to static pressure loading, the ring may be deformed.

Title: Ignition and monitoring device for a fuel-heated heat source
Inventor: ORTLINGHAUS ULRICH DIPL ING
IPC: F23N5/10
Filed: 1981-11-04
Abstract: The present invention relates to an ignition and monitoring device for a fuel-heated heat source, with a thermoelectric safety pilot which can be applied by hand and which has a thermoelement heated by a pilot burner which is fed with an ignition fuel valve, as well as a main fuel valve lying in the path to a main burner, and with a supply voltage source, dependently on which an ignition generator and a thermocurrent simulation member are switched. The object of the present invention is to provide an ignition and monitoring device with support by means of a supply voltage source, which can also be operated manually independently of the operation of the supply voltage source. This object is achieved in that there is connected parallel to the ignition fuel valve a manually operable ignition fuel valve which is provided with a contact which disconnects the supply voltage source. The technical advance which can be achieved herewith lies in the fact that the user can use the heat source even in the event of failure of the mains voltage, while the useability will not be impaired with the supply voltage source present.
Patent DE-3144720-A1 (DE)
Title: Radial sliding-contact bearing with bore, shaft or axle circumferential surface geometry matched to the deformation under load
Inventor: JARCHOW FRIEDRICH PROF DR ING
IPC: F16C23/04
Filed: 1981-11-11
Abstract: To reduce the decrease in the load-bearing capacity of sliding-contact bearings due to deformation under load and the resulting skewing and/or bending of the shaft or journal, the bearing bushes hitherto used adapt elastically to the shaft or journal contour by virtue of the pressures prevailing in the lubricating film. The minimum depth of the lubricating gap is then constant over the width of the bearing. The same effect is achieved if the bore or shaft or journal is given a tapered or convex contour. Contour matching is then effected during manufacture itself. The manufacturing process is relatively simple if the contour is approximated by a hyperboloid obtained by guiding the tool along the generator.
